摘要：

In this work, samarium-iron garnet nanopowder (Sm3Fe5O12) was obtained and characterized by TG/DTA, XRD, SEM and EDS. The synthesis of this magnetic material was carried out by the co-precipitation method, using hydrated chlorides of the rare-earth elements and ferrous sulfate. PVA was added to the calcined powder in order to facilitate the production of a toroidal compact specimen, which was submitted to sintering in the range of 1200 degrees C to 1400 degrees C, to stablish a correlation of its magnetic properties with morphology.
